I worked on creating a card game with a couple of my friends. We kept all of the cards in a Google Sheet, allowing everyone to easily edit or create new cards. Then, I wrote a script to compile the sheet into a card atlas so that it could be consumed by Tabletop Simulator. It worked amazingly well.

The only issue was that I had to run the script myself, since my friends were less technical. I'd probably see if I could setup a workflow in Github Actions to do it for me if I were to do this again.
